Summary: New superionic conductors based on polyanion-added chloride-based materials show high ionic conductivity and are suitable for use as solid electrolytes in all-solid-state sodium batteries. The materials consist mainly of an amorphous phase and Na2ZrCl6. The conductivity is likely influenced by the electronegativity of the polyanion's central atom.

Summary: Sodium-ion batteries (SIBs) have developed rapidly due to the abundance, distribution, and low cost of sodium. Sodium superion conductor (NASICON) based electrode materials are promising for sodium storage, but their low electronic conductivity limits their electrochemical performance. Strategies such as coating with carbon, reducing size, combining with other carbon materials, and doping elements have been studied to enhance the conductivity of NASICON-based cathode materials.

Summary: In this study, SiO4 was introduced to substitute PO4 in order to modulate the local environment of Mn, activating the redox activity and stabilizing the reversibility of NMCP-Si. The introduction of SiO4 resulted in enhanced rate capability and cycling stability of the electrode material. This work addresses the challenge of stabilizing the structure of Mn-based NASICONs and provides a breakthrough in understanding how to improve Na+ conductivity by regulating local structure.

Summary: This study introduces a new compositional space of argyrodite superionic conductors, Li6-xPS5-xClBrx [0 <= x <= 0.8], with high ionic conductivity and low lithium migration barrier. Bromination treatment can maintain the parent Li6PS5Cl structure within a certain range, leading to enhanced Li+ ion dynamics and a liquid-like Li sublattice. Halogen-rich compositions induce hypercoordination and coordination entropy, enhancing Li+ ion transport in the material.

Summary: Anion exchanged NiP2-xSx solid solution series were synthesized by high-energy mechanical milling, and their electrochemical properties as an anode for sodium-ion batteries were investigated. The solid solution affected the redox reactions of each end member and shifted the sodiation/desodiation potentials, which activated the reaction between P and Na ions and increased the discharge capacity. The NiP2-xSx solid solutions exhibited sequential conversion reactions with Na ions, resulting in a nanocomposite of sodiation products (Na3P, Na2S, and Ni), which effectively reduced the volume change, prevented the agglomeration of active materials, and ensured the electron and ion transport. Consequently, the NiP1.5S0.5 solid solution electrode exhibited excellent cycle stability, delivering a reversible capacity of 299 mA h g-1 after 200 cycles at a high current density of 500 mA g-1.

Summary: Polymer electrolytes are being studied for their potential as solid-state ionic conductors in future lithium metal batteries. Poly(ethylene oxide)-based electrolytes, in particular, are favored for their high ion conductivity and compatibility with electrode interfaces. However, the trade-off between ion conductivity and mechanical strength enhancement is a challenge due to the coupling between lithium-ion transport and polymer chain motion. Low temperature ion conductivity and low cation transference numbers also hinder practical applications of these electrolytes in batteries.

Summary: Aqueous rechargeable Zn-ion batteries (ARZIBs) have gained attention for their safety, high energy density, and environmental friendliness. However, dendrite formation and corrosive reactions on the Zn anode surface have posed challenges. In this study, Ga3+-doped NaV2(PO4)(3) with Na superionic conductor (NASICON) structure was used as an artificial layer to stabilize the Zn anode. The optimal NVP-Ga(0.5) layer effectively homogenized ion flux and promoted uniform deposition of zinc, inhibiting dendrite growth and parasitic reactions. The resulting batteries showed stable operation and high discharge capacity.

Summary: Layered cathode materials, such as Na-NMC, commonly used in lithium and sodium ion batteries, can experience mechanical degradation due to electrochemically induced buckling and delamination cracking of intercalation layers. The formation of kinks in the delaminated layers, resulting from severe local bending and dislocations, is observed during in situ mechanical compression experiments. This new degradation mechanism highlights the importance of addressing weak interlayer bonding to mitigate degradation in layered cathode materials.
